1. Field of the Invention

The present invention relates to a waste heat recycling and gain system, and more particularly to a waste heat recycling and gain system including an arrangement to effectively recycle or reuse the heat of the waste hot water and to save our energy and to protect our environment.

2. Description of the Prior Art

Typical cleaning processes or procedures, such as showering operations, hair washing operations, dish washing operations, etc. may use the hot water for cleaning purposes, and comprise a water supplying pipe or faucet to supply the hot water to clean various objects or members.

However, the hot water is normally flowing downwardly to the drain and the water way directly, and the heat of the hot water normally has not been recycled or reused such that the heat of the hot water is wasted.

A throttle valve 24 is disposed or attached or coupled to the outlet of the heat exchanging member 21 for controlling the outward flowing of the heated cold or hot or heat medium that flows out of the heat exchanging member 21. An evaporator 25 is disposed or attached or coupled to the throttle valve 24 for evaporating purposes and for decreasing the temperature of the heated cold or hot or heat medium, and coupled to a further heat exchanging member 26 which is disposed or arranged beside the heat exchanging member 17 for forming an auxiliary heat exchanging device 27 together with the heat exchanging member 17 and for absorbing the heat of the water flowing through the heat exchanging member 17, the heat exchanging member 26 is then coupled to the compressor 23 for allowing the compressor 23 to be coupled in series between the heat exchanging members 21, 26.

In operation, as shown in FIG. 1, the compressor 23 may compress and increase the temperature of the cold or hot or heat medium to about 60° C. and may supply the heated cold or hot or heat medium to the heat exchanging member 21 and then to heat exchange with the water flowing through the heat exchanging member 16 and to increase the temperature of the water of the heat exchanging member 16 to the predetermined or required temperature or value, the water flowing through the heat exchanging member 16 may be heated from 30° C. to about 45° C. and may supply the heated water of about 45° C. to wash or to clean various objects or members, the cold or hot or heat medium that flows through the heat exchanging member 21 may be decreased from 60° C. to about 40° C. and may then be cooled to about 10° C. by the evaporator 25.
